Swallow the Doctor — The Present and Future of Robots Inside Us
I recently finished the Silo series by Hugh Howey, a self-published collection of novellas that details life in a near-future, post-apocalyptic world where all that remains of humanity has been stuffed into subterranean silos. It has a great plot with some fun twists and plenty of details to keep the hacker and sci-fi fan entertained.
One such detail is nanorobots, used in later volumes of the series as both life-extending tools and viciously specific bio-weapons. Like all good reads, Silo is mainly character driven, so Howey doesn’t spend a lot of eInk on describing these microscopic machines – just enough …read more
Listen Up: iPhone Hack Diagnoses HVAC
We all know that guy (or, in some cases, we are that guy) that can listen to a car running and say something like, “Yep. Needs a lifter adjustment.” A startup company named Augury aims to replace that skill with an iPhone app.
Aimed at commercial installations, a technician places a magnetic sensor to the body of the machine in question. The sensor connects to a custom box called an Auguscope that collects vibration and ultrasonic data and forwards it via the iPhone to a back end server for analysis. Moving the sensor can even allow the back end to …read more
First Raspberry Pi Zero Hack – Piggy-Back WiFi.
And we have the first Raspberry Pi Zero hack! In less than 72 hours from the official release announcement [Shintaro] attached an Edimax WiFi USB Adapter directly to the USB solder pads on the Pi Zero. He couldn’t bear to disturb the small dimensions of the Pi Zero by using the USB On-the-Go (OTG). The OTG is needed to convert the micro-USB connector on the board to a full USB-A connector.
The case was removed from the Edimax and the device and Zero wrapped in Kapton to insulate the exposed solder points. Power was taken from the PP1 and PP6 …read more
The Internet of Reflow Ovens
Using a toaster oven to reflow solder isn’t a new idea. But [Sukasa] wanted something that had more features and improved appearace. So he married a Netduino, a toaster oven, and some solid state relays to made a clean-looking reflow oven. His goal was to have nothing look like an overt modification to a casual observer. Inside, however, the oven now has a network connection for system status via a Web browser or JSON.
The new brains of the oven are a Netduino Plus 2 and an I2C port expander that connects to a few extra I/O devices. The challenging …read more
Thorough Macbook Charger Teardown Reveals Some Complex Circuitry
Apple has a reputation in the tech world as being overpriced, and nowhere is that perception more common than in the Hackaday comments. The standard argument, of course, is that for a device with equivalent specs, Apple charges a lot more than its competitors. That argument is not without its flaws, especially when you consider factors other than simple specs like RAM and processor speed, and take into account materials used and build quality. But, as this teardown by [Ken Shirriff] shows, Apple’s attention to detail extends beyond simply machining Macbook bodies out of aluminum.
In his teardown, [Ken Shirriff] …read more
